To all whom, it may concern,.-

` Be it known that I, VICTOR B L'rHcEN, a subject of the King of Prussia, residing at Freienwalde on the Oder, Prussia, German Empire, have invented certain new and useful Improvements in the Ornamentation of Glassware and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled i`n the art to which it appertains to make and use the same, reference being had lto the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this speciiicatiou.

The invention relates to a novel process of producing colored designs on glass, ceramic products, and other articles; and it has for its object the production of imitation `painted glass that possesses all the characteristic features of the genuine painted glass.

The invention has for its' further object to provide a Ameans whereby glass or glassware, ceramic products, or plaster casts may be rapidly ogrnamented or decorated at comparatively little expense.

In the production of colored ornaments or pictures I employ in all cases artificially-colore'd transparent gelatinous substances-has, for instance, collodion or gelatineeither of vegetable or animal origin, which, when applied to the glass, either by causing the same to iiow thereon while in a tluid state or otherwise, will form atransparent or translucent Vcolored coating or layer, and whereby section lines, or boundaries, or outlines may be formed on plates of glass either by means ot" metal foil, bythe helioplastic or other like process, or by means of the previouslylapplied colored coating, in the latter case any excess being removed by cutting` out or scraping.

In the ornamentation of glass or glazed or enameled surfaces, the surfaces to be ornamented must first be treated or cleaned in the same manner as for photolithographic purposes, (a treatment which is well known and need not here be described) to cause the gelatinous substance to rmly adhere to the surface to which it is applied. The drawing, and consequently the outlines of the colored pattern in black or other dark tint, is applied by hand or by mechanical means, in the well-known manner, to the surface to be ornamented before vthe colored gela-tinous substanceis applied thereto. In the ornamentation of glass I prefer to apply the design to Vthe back of the plate, though it may be applied to the front thereof, and in either case the said design willbe seen through the colored gelatinous coating, so that the whole will have the appearance of painted f In the drawing, i indicate portions of the back of thev glass plate a, upon which the design is applied in theusual colorsay black, for instancethe corresponding front portions being covered by a layer or section, o, that separates the sections x from one another.

The sections o may be formed in various ways, as above described-for instance, by forming upon the outer face of the plate of glass, previously treated as described, a ilm or layer of uncolored gelatine, and allow the same to cool and become stiff or rigid, then removing those sections, thereof which are afterward to be lled with colored gelatine.

After the several or individual sections or elds4 of the painting have been produced as described, they are filled with gelatine of the desired color or colors. Vhen two or more different colors are to be brought in immediate contact in the same field or section, the latter is first coated with gelatine of one color; then those parts of the section which are to be of a different color are removed after the gelatine has become stiff, and the places are coated with gelatine ofthe color required. The smaller portions of a section may also be coa-ted by the application of the gelatine with a brush, and the coat or layer of gelatine may be composed of several superposed layers of gelatine IOO When the ornamentation of the article has transparent or translucent coating upon an been completed, the gelatine is coated With a object to which the design has previously been transparent varnish, or a second plate of glass applied, as set forth, and that, in combination may be applied to the ornamented side of a with saiddesign, will bring out the character glass plate to protect the gelatine.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent of the United States, is-

The process of producin g colored ornanienta- I described, for the purpose specified.

In testimony whereof I ax my signature in' presence of two witnesses.
